演示在用java連接Sybase ASE數據庫。用了一個簡單的java程序作試驗。
第一步：獲得jdbc for sybase驅動程序
下載JDBC驅動：http://www.sybase.com/detail?id=1009726
也可到CSDN下載：http://download.csdn.net/source/2697077
有jConnect6.05和jConnect5.5兩種。jConnect6.05中包含jconn3.jar包，jConnect5.5中包含jconn2.jar包。建議最新的Sybase驅動jconn3.jar。不過我的這個例子很簡單，兩者都可以用。
下載：jconn3.jar ，下載：jconn2.jar
第二步：設置環境變量CLASSPATH
將下載下來的jconn2.jar或jconn3.jar放到目錄D:\sybase\Shared\lib下。將環境變量CLASSPATH設置為：D:\sybase\Shared\lib\jconn2.jar
set CLASSPATH=.;d:\sybase\shared\lib\jconn2.jar; (注意：第一個“.”，這個代表當前目錄。)
第三步：編寫一段簡單的java程序。
下面的這段程序用jconn2.jar連接Sybase ASE15.0.3數據庫並提取master數據庫中的用戶表的ID和name兩列信息。
Sybase ASE數據庫的ip地址為：192.168.0.168，端口：5000。登錄sa的密碼為：sybase
執行：select id,name,crdate from dbo.sysobjects where type='U' 這條語句返回當前數據庫（這在url中指定！）中的用戶表的id和name列。
import java.sql.*;
import java.util.*;
public class Conn2ASE {
public static void main(String[] args) {
try {
Class.forName("com.sybase.jdbc2.jdbc.SybDriver").newInstance();
String url = "jdbc:sybase:Tds:192.168.0.168:5000/master";// 數據庫名
Properties sysProps = System.getProperties();
sysProps.put("user", "sa"); // 設置數據庫訪問用戶名
sysProps.put("password", "sybase"); // 密碼
Connection conn = DriverManager.getConnection(url, sysProps);
Statement stmt = conn
.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,
ResultSet.CONCUR_UPDATABLE);
String sql = "select id,name,crdate from dbo.sysobjects where type='U'"; // 表
ResultSet rs = stmt.executeQuery(sql);
while (rs.next()) {
System.out.println("oject_id:"+rs.getString(1)+",oject_name:"+rs.getString(2)); // 取得第二列的值
}
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
將上面這段代碼保存到：d:\sybase\shared\demo\Conn2ASE.java
第四步：編譯java源文件為class文件
javac.exe Conn2ASE.java
C:\Documents and Settings\Administrator>cd /d d:\sybase\shared\demo
D:\sybase\Shared\demo>set CLASSPATH=.;d:\sybase\shared\lib\jconn2.jar;
D:\sybase\Shared\demo>D:\sybase\WorkSpace\JDK1.5.0_15\bin\javac.exe Conn2ASE.jav
a
D:\sybase\Shared\demo>dir
驅動器 D 中的卷沒有標簽。
卷的序列號是 24C3-2A76
D:\sybase\Shared\demo 的目錄
2010-09-15 17:08 <DIR> .
2010-09-15 17:08 <DIR> ..
2010-09-15 17:08 1,683 Conn2ASE.class
2010-09-15 17:02 1,107 Conn2ASE.java
2 個文件 2,790 字節
2 個目錄 18,468,270,080 可用字節
第五步：執行java程序連接Sybase ASE數據庫，並顯示查詢結果
java Conn2ASE
D:\sybase\Shared\demo>java Conn2ASE
